To all cli/wm t may concern:

Be it known that I, Roi D. CHEEK, a citizen of the United States, residing at Olney, in the county of Richland,` State of Illinois, have invented certain new and useful Improvements in lVheat-,Se'paratorsg and I do hereby declare the following to be a full, clear, and eXact description of the invention,such as will enable others skilled in the art to which Vit appertains` tomake and use the same. l i

rlhis invention has specialreference to novel and useful improvements in separators and more particularly to a wheat separator. Y

The essential object ofthe invention is evolved in the provision of a novel separating mechanism by `which onion seed and similar seed will be separated from the wheat. v

The invention further comprehends an improved separator of the agitating type embodying novel separator sieves so that the wheat or grain is caused to be discharged in a tortuous path between the sieve bars under the agitation instead of depending upon a gravity action, the devicebeing designed for special use after the wheat has been separated once, and the dust,'straw and screenings removed, although the device may be used as an originalseparator and efficiently serve to remove the dust, straw and screenings as well as the onion seed from theV wheat ata single operation.

With the above and other objects in view, the invention resides more particularly in the peculiar combinations and arrangements of parts as will be partly illustratedas a preferred embodiment in the accompanying drawings and described in the specification, although the invention is protected for all desirable changes and uses within the scope of the invention as claimed. e

ticularly illustrating the separating action and paths of the materials. Fig. 9 is an end elevation of the sieve plates in operative relation. Fig. 10 is an enlargeddetail perspective view showing one of the guard plates for discharging the grain under the sieve bars and preventing displacement thereof at the sides of the sieves.

In illustrating the preferred embodiment of the invention, my improved wheat separator is' shown as embodying a base frame 10 having at its cornersthe posts 11 and 12 respectively, the posts 11 being located at the receiving end and the posts 12 at the discharge end. Braces 13 connect the respective corner posts transversely and longitudinally and serve to support therebeneath through the instrumentality of spring bars 14, consisting of bars of wood or metal of suitable cross section,` the sieve structure 15. These spring bars or supports- 14 are connected to the cross braces of the frame and the sieve structure or frame 15 is supported in a position inclining from the top of the receiving end toward the bottom of the discharge` end and such structure is thereby` supported for agitation.

The sieve structure embodies a bottom plate 16 which is preferably made of sheetiron' and slotted longitudinally at spaced parallel points as shown at 17 to provide alternate spaces and sieve bars 18, the bars being preferably of an inch wide andthe spaces or openings i of an inch wide in practice, although such proportions may be varied in accordance with the size of the grainl The ends of the plate 16 are solid or closed as shown at 19 `and 20 respectively, thus reinforcing the structure by forming uniting means for the bars and providing receiving and discharging portions for the wheat to be separated and the onions and like particles or materials which will be separately discharged. The bars 18 are further connected by transverse braces 21- in the form of strips produced by integral parts of the plate which may be stamped or cut in the form described. These braces 21 serve to support the top sieve plate 22, the bars 23 of which are arranged in opposite relation to the bars 18 so that the bars 23 will overlie the spaces or openings 17 of the bottom sieve plate and the spaces 24 will overlie portions of the bars 18, the bars 23 and the spaces 24 being preferably of an inch wide to correspond with the aforesaid measurements for this purpose. Thus, the top plate 22 willbe provided with as many bars as there are openings in the bottom plate and as many openings within the area ofthe sieve frame as there are bars in the bottom plate so that the longitudinal edges of the bars 23 willpartly overlie; the barslS, thus forming tortuous channels controlling the paths of the separated grain and refuse, including the straw, dust and screenings, while the onions and larger materials are retained between the top bars.

ItV will also be observed that the top portion of the lplate 22 is' solid as shown at .25 thus'y forming a connection between the bars 23, while the openingsA or spaces 24 communicate with the ends? of the bars 23 at the discharge en d of the machine. The barsQB are connected' to the crossbraces ofthe plate 16 soas to'be spaced-above the bars 18, through the medium of' thebolt's'26 with interposed washers 27 engaged on `the bolts, the washers being preferably 'of-'an inclrthicl-,to properl'y space thetop'fand bott'oin barsfso that the narrow cha'nnelsfth'us"provided for the passage of the grain and refuse will be' asy Y wide asV the diiference between the lengthof a vgrain andthe' diameter of such grain, whereby the grain may freely pass through without clogging. Guards 28 are arranged att'he sides of thelower sieve plate to discharge the grain on to the sieve and also to prevent displacement ofthe same at the f sides asthe structure is agitated in a' 1nanner to be hereinafter described.: Eachguard consists of a sheet'n'ietal plate bent to pro vide a vertical outer portion 29 whichat its upper' edge is directed or bent downwardly to form an inclined portion Aor aprony 30 which isv then bent in" an angular direction outwardly and downwardly as shown at 31, the parts being connected'b'y Vfastenin'gfmeans 82"v tothe outer bars 17 ofthe sieve plate so that the top edgesl of theguvards will extend slightly abovefbu't substantially'in alinement horizontally 'with"theupperfaees of the top sieve barsy or plate'lforniing the same.

In order to agitate the sieve structure, a shaft 33 is' supported` atV the receiving end of the separator through the instrumentality oftheposts 1-1,`such shaft havinga drive pulley 34 at one Vendl beyond the frame whereby it may be rotated from any source ofpower, while an eccentric is fixed to the: shaft centrally to engage the receiving end'of the sieve frame for agitating the same' longitudinally, it being understood that the sieve frame is carried by the spring bars'14 which are bowed and flexibleto permitvr the necessary movement, owing ytothe factl that' theirends' are anchored to the cross bracesof' the frame proper. The sieve pan isindicated by the numeral 36 and Aisnsupported within the frame 15 below the sieve structure to receive the grain-'and refuse,

with ythe exception of onions and like materials or particles, so as to discharge the same in frontofthe fan casing 37 which is arranged at the lower end of the sieve frame.

Affan38 is iiXed to a shaft 39 carrying at -one end a pulley 40 around which and a pulley 41 fiXed to the end of the shaft 33 opposite to the pulley 34, is engaged an endlessbelted' drive member 42, thus serving to Y actuate the fan upon rotation being imparted lto the shaft 33Q The fasteningdevio'sr't'humb screws 32'whichy serre to seciire the guard tothe bottom sievelplate are also engaged through the sides of4 the sieve f thereof which are extended' above the braces,

the wheat being; supplied tothe feed box through the medium of a spout 44 and discharged through a feed opening 45 onto the sieveh The opening 45'is located longitudin'ally` of lthe box and Vthe box is ,provided with affeed regulatorrwhich serves to permitthe'dis'charge of the proper curantity of wheat" or to c'tr off the supply entirely, such means embodyingV a ,plate 46 slidable in gnideways Y47 carried atthe inside of the boX ,near its ends and yprovided with rack teeth or bars 48`on its inner face near each endl` A shaft 49, isrotatably journaled horizfont'allythrough .the boX andi carries pinions 50? ineshingy with vthe raclrteeth or bars 4S whereby rotationuof the shaftthro'ugh the medium of a hand crank 51 at one end of the shaft will permit raising and lowering of the slide.

A- trough 52'is iitted to the discharge end of the sieve, Abeing `arranged beneath the ppermost sieve plate to discharge the onions roo andfniaterials traveling therewithatvone side of thel frame, the trough being extended lat'- erallyfor thisrpurpose, so that suitable receptacles may be positioned atthe discharge end ofthe trough, which is open, for the collection thereof. that the space between the upper and lower screenis less than the Vspace between the bars of the upper screen the onion seed, which areof larger diameterthan the wheat, will roll down between said` bars whilethe wheat grains will work sidewise betweenA the upper and lower screens. Y The' slots 4ofthe lower screen are madewider than the distancebetween the screens in order that a grain will `ldrop through the flower slot whether presented transversely tothe slotl or in alinement therewith. Thus as the sieve structure is agitated during a constant and uniform supply of wheat', the grains will be shaken Voff of the :bars 23 and on to the bars 18,\so that the grains'will By reasonbf the fact pass sidewise through the tortuous channels between the bars oi' the upper and lower plates and on to the pan 36 whence it will be discharged into the fan casing 37. The blast will then separate the dust, straw and screenings from the grains while the wheat will pass downwardly through a discharge spout 58 by gravity. The onions and large;I particles which cannot pass through the channels will be retained on the bars 18 and between the bars 23 which form substantially longitudinal channels so that the material will be conveyed into the trough 52 and afterward discharged at one side of the machine with the waste material. It will thus be evident that I have provided an eX- trernely eflicient and simple wheat separator, which by serving to separate the onions and the like from the wheat as well as to remove the straw, dust and screenings, will be instrumental in the production of a much cleaner and better product, desirable alike by farmers and mills.

I claim:

In a wheat separator, the combination with a frame structure and vertically arranged bowed spring bars carried thereby, both ends of each bar being anchored, of a sieve having its ends connected relatively near the upper and lower ends of the bars respectively, and means for agitating the sieve.

In testimony whereof, I aiiix my signature, in the presence of two witnesses.
